Heredity

THE author, who is professor of zoology in the University of Michigan, states in his preface that this volume represents a course of lectures delivered for several years to large classes of students who were admitted “without prerequisite.” Doubtless for this reason the presentation of the subject matter is more or less popular, and in consequence somewhat dogmatic and superficial. Besides the phenomena of heredity proper, it deals with such topics as problems of population, immigration, and eugenics. Though by no means a poor book, it is rather mediocre and lacking in distinction. Probably it is better adapted to the audience for which it was planned than to an English one, but if it should help to stimulate interest in such matters it will have served a good purpose.Heredity.By Prof. A.
